No, there's no description field on a Databricks job. People have been asking for it for years. Still nothing.

Here's what I've seen people do instead:

Tags work for short stuff. You can slap key-value pairs on a job owner, team, what the parameters mean if you keep it brief. They show up in the UI and you can query them through the API.

If you use Databricks Asset Bundles, you can put comments in the YAML next to each parameter. Doesn't show up in the UI, but anyone touching the code will see it, and it stays version-controlled.

Hope this helps! If it does, could you please mark it as "Accept as Solution"? That will help other users quickly find the correct fix.
